How can you use the engineering design process to construct a probe to hit a specific target?
To see if there’s water on the moon, NASA sent the Lunar Crater Observation and Sensing Satellite, or LCROSS, hurtling into a crater near the moon’s south pole. The collision sent up a plume of dust and gas over 10 kilometers (6 miles) high. Scientists studied this plume to see if there were any signs of water in it. Just as the success of LCROSS depended on hitting the crater exactly, success in this design challenge activity depends on being able to hit a target accurately and consistently.
In this challenge, students follow the engineering design process to modify a cup to carry a marble down a zip line; test their cup by sliding it down the zip line; release the marble; try to hit a target on the floor; and use test results to improve their system.
